SUPERI-EA'IER FOR VACUUM-CONDENSERS.

Application filed March 14, 1908.

T 0 all whom it may concern:

Be it known that we, CHARLES T. ROGERS and RAYMOND R. Roenns, citizens of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Superheaters for Vacuum-Condensers, of which the following is a specification, reference being had therein to the accompanying drawings.

In treating matter, such as milk, syrup and the like, in vacuum condensers where it is de sirable or necessary at some stage of the process to reheat the mass or superheat it by the introduction of steam, it is essential that the heat be evenly distributed. It is also advantageous oftentimes to agitate the contents of the condenser while being thus heated, and this is especially true in the process of condensing milk.

This invention relates to means for introducing steam into a condenser and distributing it evenly through its contents and for agitating the contents at the same time. As herein shown, it is especially adapted for a vacuum condenser for milk, and is known to the trade as a superheater.

The invention consists in the matters hereinafter set forth, and more particularly pointed out in the appended claims.

In the drawings, Figure 1 is a view in vertical section of the lower portion-of a vacuum condenser provided with a superheater embodying features of the invention. Fig. 2 is a view of the superheater in section on line acm of Fig. 1. Fig. 3 is a view in elevation, enlarged, of the heater itself. Fig. 4 is a View in detail .of a steam mouth piece.

Referring to the drawings, 1 indicates the interior bottom wall and 2 the outer or steam jacket of a conventional vacuum condenser, the base of which is preferably hemispherical or concave. The steam jacket 2 may have a vertical boss 3 at one side of its center or other provision may be made for the intro duction of a substantially vertical steam inlet pipe 4 having suitable fittings for making a tight joint where it passes through, as an inner flange 5 adapted to seat itself closely on the inner wall of the condenser, and an outer packing ring or gasket 6 held by the clamping ring 7 screw-threaded on the outer end of the pipe. A tee 7 or other connection is added for attaching any pipe from a suitable source of steam.

The inner end of the inlet pipe is exteriorly Specification of Letters Patent.

screw-threaded to receive a tapered nozzle 9 which is bent between its ends horizontally toward the center of the condenser. A spider 10 on its horizontal arm, preferably integral therewith, terminates in a flange 11 concentric with the nozzle, and an open-ended horizontal cylinder 12 is secured therein, as by screw-threads 13.

The spider itself has a plurality of large apertures 14 which form inletsto the cylinder 12. A fan-shaped mouthpiece 15 whose outlet 16 extends diametrically across the cylinder is screw-threaded or otherwise secured to the end of the nozzle, preferably in the upright position indicated.

In operation, steam forced through the nozzle, which is always completely immersed in the contents of the condenser, causes a currentor movement in the contents through the cylinder, while the thin flat jet of steam gets into intimate contact with the matter under treatment. Thus there is a thorough distribution of the steam and at the same time a mechanical mixing or stirring which efiectually breaks up and disintegrates the mass, thereby preventing lumping or caking. This latter condition is peculiarly frequent in the process of condensing milk wherein steam is introduced through ordinary nozzles or jets, the milk merely being heated round the jets and becoming caked, so that the outer or more remote portions are unaffected.

The peculiar motion imparted to the milk by the superheater herein shown not only distributes the heat evenly, but likewise renders the finished or condensed product of finer, more uniform grain or consistency than is ordinarily obtainable. While especially adapted for milk condensing apparatus, it

limit ourselves to any particular form or arrangement of parts.

What we claim as our invention is 1. A superheater for a vacuum condenser comprising a steam inlet pipe adapted to be secured in the condenser wall, a tapered nozzle secured to the inner end of the pipe and bent to extend horizontally toward the center of the condenser, an apertured spider on the nozzle terminating in a flange concentric with the nozzle, an open ended cylinder secured at one end in the flange with its discharge end extending beyond the nozzle, and a fan shaped mouthpiece on the nozzle extending diametrically across the cylinde H 2. A superheater for a vacuum condense comprising a steam inlet pipe adapted to be .secured in the condenser wall, a tapered nozzle and a fan shaped mouth piece on the nozzle extending diametrically across the cylinder.

vacuum condenser of a superheater comprising a steam inlet pipe extending through the I wall of the condenser near-the bottom, a

tapered nozzle secured to the inner end of the pipe and bent to extend horizontally toward the center of the condenser, an ,apertured spideron the nozzle terminating in a flange concentric with the nozzle, an open ended cylinder secured at one-end in the flange with its discharge end extending beyond the nozzle, and a fan shaped mouthpiece on the nozzle extending diametricallyacross the cylinder.

4. The combination with the base of a vacuum condenser of a superheater comprising a steam inlet pipe extending through the 'wall of the condenser near its bottom, and having a flange integrally formed thereon adapted to closely fit against the'inner, side of the condenser, a gasket on the outer end of the pipe, a clamping collar screw- 3 threaded on the pipe against the gasket, a tapered nozzle secured to the inner end of the pipe and-bent to extend horizontally toward the center of the condenser, an aper- Y tured-spider on the nozzle terminating in a 4 '3. The combination with the base of a flange concentric with the nozzle, an open ended cylinder secured at one end in the flange with its discharge end extending beyond the nozzle, and a fan shaped mouth piece on the nozzle extending diametrically 4 across the cylinder.

I In testimony whereof we affix our signatures in presence of two witnesses.
